* * * * * This rapid sketch of the history of Isis and Serapis shows that these divinities were worshiped in the Latin world for more than five centuries. The task of pointing out the transformations of the cult during that long period, and the local differences there may have been in the various provinces, is reserved for future researches. These will undoubtedly find that the Alexandrian worship did not become Latinized under the empire, but that its Oriental character became more and more pronounced. When Domitian restored the Iseum of the Campus Martius and that of Beneventum, he {86} transferred from the valley of the Nile sphinxes, cynocephali and obelisks of black or pink granite bearing borders of hieroglyphics of Amasis, Nectanebos or even Rameses II. On other obelisks that were erected in the propyleums even the inscriptions of the emperors were written in hieroglyphics.[35] Half a century later that true dilettante, Hadrian, caused the luxuries of Canopus to be reproduced, along with the vale of Tempe, in his immense villa at Tibur, to enable him to celebrate his voluptuous feasts under the friendly eyes of Serapis. He extolled the merits of the deified Antinous in inscriptions couched in the ancient language of the Pharaohs, and set the fashion of statues hewn out of black basalt in the Egyptian style.[36] The amateurs of that period affected to prefer the hieratic rigidity of the barbarian idols to the elegant freedom of Alexandrian art. Those esthetic manifestations probably corresponded to religious prejudices, and the Latin worship always endeavored to imitate the art of temples in the Nile valley more closely than did the Greek. This evolution was in conformity with all the tendencies of the imperial period. By what secret virtue did the Egyptian religion exercise this irresistible influence over the Roman world? What new elements did those priests, who made proselytes in every province, give the Roman world? Did the success of their preaching mean progress or retrogression from the standard of the ancient Roman faith? These are complex and delicate questions that would require minute analysis and cautious treatment with a constant and exact observation of shades. I am compelled to limit myself to a rapid sketch, which, I {87} fear, will appear rather dry and arbitrary, like every generalization.
